bins-engines, and has for its object a construction in which ample provision is made for the escape-of the expanded steam or other propulsive medium after it has operated upon and exerted its fullest force upon the piston, so that it will not check or retard the piston, and thus enabling it to exert its highestspeed and force with the least possible propulsive medium.

The invention also contemplates certain other improvements and advantages which are attained by the peculiar construction, combination, and arrangement'of parts, as

- will be fully set forth in the following specification and pointed out in the claims, reference being had to the drawings, in which Figure 1 is a perspective View of our engine complete.

Fig. 15 is a detail per- 5 spective view of one of the cranks for operating the valves, and Fig. '16 is a detail sectional view drawn on the line 16 16 of Fi 10. In constructing an engine in accor ance with our invention'we employ a casing A, A and a rim A ail being securely bolted to form a steamtight compartment. One end of the rim is of a larger diameter than the opposite end, and fitting therein is a divisional plate C, c which divides the. casin into two compartments D and I), one or which, D, forms a live-steam chamber, and the other, I), together with a cylinder to be explained later, terms exhaust and piston chambers.

Positioned within the s ace D is a doublerim cylinder E, which is tightly held between one head of the casing and the divisional plate, which thus divides the chamber D. into three com artments D D and D, the compartment 4 providing a piston-chamber and spaces D and D annular exhaust-chambers which communicate with the piston-chamhers through ports F and G, arranged in and extending through the rims on lines substantially tangential to the circumference of the rims. vThe ports F establish commun'ieation between the iston-chamber and the exhaust-chamber. 3 and the ports G between the pist'on-chamber and the exhaustchamber D The latter ports extend through ribs H, cast integral with the rims of the cylinders, and do not communicate with the chamber 1). i

.Journaled in suitable hub-bearings in the heads of the casings and extending through the partition-plate C is a shaft I, having a piston J kelyed thereon, which snugly fits Within the c amber D, and around its entire periphery the piston is formed with a plurality .of alternating seats or rows of steam-pockets J and J The pockets J in alternate rows are deepest at one end to provide a broad surface J against which the steam strikes to drive the piston in one direction, while the pockets J? of each alternate row are deepest at the opposite end, =thus: providing a broad surface J 4 for the impact of steam-to drive the piston in the opposite-direction.

. Arranged within the chamber D of the cas ing at diametrically-opposite points are valve-cylinders K, and in order to provide for a free passage of the expanded steamsides and in alternate a rotary valve Lfor controlling the steam orts, and in order to provide a free passage or the steam throughoutthe entire length of the cylinders we construct each valve of a shaft L, having arms or segmental disks L and L radiating therefrom in alternate directions to cover the steam-ports K and K res ectively. The shafts are also provided wit a series of arms L, which engages the opposite sides of the cylinders to those in W ich the ports are arranged, and thereby providing a counterbalance for the shaft to N, held in the live-steam chamber D and old it in perfect alinement and insure the arms or disks being snugly fitted over the ports. It is of course understood the interior of the cylinders are ound perfectly smooth, especially at the points surrounding the discharge-ports, so as to provide seats for the arms or disks, and if it should be found, desirable the cylinders could'be provided with raised seats for the arms or disks, as shown in Fig. 14 of the drawings.

One .end of each valve-shaft is extended through a 'stufling-box a, in the head of the casing, and to their extreme ends are connected crank-arms M, to which are connected links M, whose op osite ends are connected to arms M of, a d fsk M that is revolubly mounted u on the journal box or hub of the casing-hea and extending from the disk is a controlling-lever M carrying a ratchetlever which works-upon arack-bar fastened to the casing. It is obvious that by throwing the lever either set of ports in the cylinder may be simultaneously opened orclosed, or both sets closed, as may be desired.

One end of each valve-cylinder extends throu h the divisional plate C and is con necte in any suitable way to a steam-box each box has a port N, that is controlled bya slide-valve N operatin 'in guideways N upon the exterior of the ,oxes, and' operated by a crank-arm 0, formed inte ral with or held upon the inner ends of roc r-shafts O, journaled in the head of the casing adjacent the live-steam chamber, and in; stuffingboxes a held to,-the" casing-head. Upon the outer ends of the shafts are held cranks O to which is connected one end of links. 0 whose opposite endsare connected ,to pit- ,man-rods O, extending'from an eccentricstrap 0 that is held. upon an eccentric-disk 0, carried by the shaft 1, and by which the valves are intermittently operated to open and close the ports.

In the drawings we have shown the ports in the upper valve-boxes open and those in the lower boxes closed, which arran ement rovides for an alternate admission 0 steam into the boxes-;,but, if desired, we may by changing the position of the crank O adjust the valves so that they will be successively allel-arranged arms between which operate the outer ends of the cranks O, and in order to decrease friction between the crankearms and the' arms of the valves we provide the cranks with sleeves which fit between the parallel arms, as shown most clearly in Figs. 11 and 15.

Connected: to the exhaust-chambers D and D are pipes P and P, respectively, which connect with an exhaust-separator Q, from which the exhausted steam: finally escapes through a pipe R. The separator is divided into three compartments Q Q Q,

and the compartments Q and Q communicate with the pipes P and P, respectively, and the compartments with the compartment Q through openings Q, that are normally held closed by spring-pressed valves S. The purpose of this peculiar construction of separator provides against the back pressure of the expanded steam and keeps either of the exhaust-chambers D and D perfectly clear whenthe piston is operating -1I1 one direction or the other, and therefore completely controlling the expanded steam and holding it from again entering the casing and'coming into contact with the piston.

It will be readilyunderstood that when the piston is working in one direction the steam will escape through one of the exhaust-pipes and thence into one of the compartments in the separator and pressing against the lower side of the valve will raise it and readily escape through the opening and finally out through the pipe R. The opposite valve in the meantime remains'within its opening and prevents the admission of steam into the opposite compartment and back into the casin The operation 0 our invention is as follows: We will assume that the piston is being driven in the direction indicated by the arthe pockets J of the piston, which drives it in the direction indicated by the arrow, and after the piston has revolved a distance about equal to the length of one pocket the latter;

will be brought into register with the ports F, through which the steam escapes into the space D and finally out through the pipe P into the separator. Of course it' is understood that the valves have been previously set to open the ports K and close the ports K Now should'it be desired to operate/or drive the piston in the opposite direction, or that indicated by the arrow 2 in Fig. 3 of the drawings, the valves are shifted so as to premit the escape of steam through the nozzles K into the pockets J from which it escapes through the ports G into the compartment l) and finally out through the pipe P to the separator. V

In Fig. 3 of the drawings we have shown all of the valves set toopen the ports K which is the position they are held in, when the piston is being driven in the direction indicated by the arrow 1; but in this view the section is arranged on an irregular line to illustrate one-half of the view as being drawn through one set of ports and pockets and the lower half through the adjacent set of ports and pockets, this being done for the purpose of economy of illustration.

The ribs or divisional walls formed by the pockets in the piston are provided with circumferential and lateral grooves, in which are held spring-actuated packing-strips J,

as shown most clearly in Figs. 6, 7, and 8 of i the drawings.

From the foregoing it will be seen that we provide an exceedingly simple and highly efficient device for the purposes stated, and further comment is thought unnecessary.
